Question

12x²+18x+42/18x²+12x+58=2x+3/3x+2 Solve

Answer 1

Answer:

x = 9

Step-by-step explanation:

12x²+18x+42/18x²+12x+58=2x+3/3x+2

Doing cross multiplication

=> (12x² + 18x + 42)(3x + 2) = (18x² + 12x + 58)(2x + 3)

Dividing by 2 both sides

=>  (6x² + 9x + 21)(3x + 2) = (9x² + 6x + 29)(2x + 3)

=> 18x³ + 12x² + 27x² + 18x + 63x + 42 = 18x³ + 27x² + 12x² + 18x + 58x + 87

Cancelling  18x³ + 12x² 27x² + 18x from both sides

=>  63x + 42 = 58x + 87

=> 5x = 45

=> x = 9
